This app is such a gift

I’ve been using this app for at least 12 years and it has transformed my understanding of the female reproductive system. I am a nurse and the way this app explains the amazing coordinated events that take place every month in our bodies gave me an even deeper understanding and appreciation of the dynamic human body. I have PCOS and struggled to get pregnant and charting my basil body temperature was a game changer. My daughter is now 9 years old :-)
Charting my temperature was by far the most accurate method! I also cross referenced with the ovulation kits and was able to pinpoint exactly when I ovulated with the slightest increase in body temp. I highly recommend this app.

My go to app - been using for 5 years!

Great app, tracks amazingly well and I use it to track my fertility. Helps me plan when we need to use condoms or avoid sex so I don't get pregnant.

Also helped me know that I was more than a few days late when I got pregnant! I wouldn't have known for sure otherwise - and I was able to track my average cycle time and see that I was even later than my latest cycle date. Really like that feature cause my cycle ranges from like 26-32 days.

Also when every doctor asked me the date of my last period, I had an exact date thanks to this app. Super helpful.

I love adding in notes of how I feel and describing specifics about that day or sex. I do look back and track how my moods are to remind myself that it's just normal Pms.

Pregnancy mode has been helpful - knowing how far along I was helped me figure out my symptoms. It turned out to be a miscarriage but even so I was able to note how I felt the whole time. Hoping this will help me compare next time I'm pregnant.

A must have.

I'm a 35 year old mom, been using this app since early 2010, almost 7 years. Granted I forget to use it a lot because I've learned when to expect the visit, but when I do use it, A+++. It helped me figure out the best times for family planning and each time I've conceived (twice now) it happened on the first attempt. I honestly think without this little program I'd have less knowledge about my body. This app has told me loads of info on the female reproductive system I never knew! I'd recommend this to ladies to track their bodies, or trying to convince.
